TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VHCV573FT,TC74VHCV573FK
Octal Schmitt D-Type Latch with 3-State Output
The TC74VHCV573 is an advanced high speed CMOS OCTAL
LATCH with 3-STATE OUTPUT fabricated with silicon gate
TC74VHCV573FT
C2MOS technology.
It achieves the high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power
dissipation.
This 8-bit D-type latch is controlled by a latch enable input (LE)
and an output enable input ( OE ).
When the OE input is high, the eight outputs are in a high
impedance state.
Input pin have hysteresis between the positive-going and
negative-going thresholds. Thus the TC74VHCV573 is capable of
squaring up transitions of slowly changing input signals and
provides an improved noise immunity.
TC74VHCV573FK
Input protection and output circuit ensure that 0 to 5.5 V can be
applied to the input and output (Note) pins without regard to the
supply voltage. These structure prevents device destruction due
to mismatched supply and input/output voltages such as battery
back up, etc.
Note:
Output in off-state.

Note1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
